Specification of Letters Patent.

Patented Dec. 20, 1910.

Application filed May 19, 1909. Serial No. 496,874.

To all whom it may concern: a

Be it known thatI, FRANK A. STANLEY, a citizen of the United States,residing at Little Rock, in the county of Pulaski and State of Arkansas,have invented certain new and useful Improvements in Stop and DrainCocks, of which the following is a specification.

My invention relates to new and useful improvements in stop and wastecocks, and has for its principal object the production of a simple andeliiciently operating device of this kind, adapted for ready attachmentto the service or supply pipe, whereby the supply of water to a housemay be cut of]? at will and both the hot and cold water pipes drained ofthe waste water through the employment of but one stop or waste cock.

With the foregoing and other objects in view, that will readily appearas the nature of the invention is better understood, the same resides inthe novel features of construction, combination and arrangement ofapplication of the invention, the service pipe as well as the hot andcold water pipes being shown conventionally. Fig. 2, is a centrallongitudinal sectional view of the invention, the revoluble valve memberor plug being shown in one of its positions. Fig. 3,,is a horizontalsection, taken on the plane indicated by the dotted lines 33 of Fig. 2.Fig. 4, is a similar view, the valve member or plug being shown in itsother position. Fig. 5, is a central transverse sectional view, on theline 5-5 of Fig. 3. Fig. 6, .is a detail plan view of the valve casing.

In the embodiment illustrated, which is for illustrative purposes onlyand therefore not drawn to scale, the numeral 1 indicates the service orsupply pipe, the same being represented as extending through thebasement of the building, and 2, the improved stop and waste cock,arranged at a suitable point of the supply pipe.

The numeral 3 indicates the boiler, which may be of any desirablepattern and which is conventionally shown only, as it does notconstitute a part of the invention.

A cold water pipe 4, is shown for estab-' lishing communication betweenthe service or supply pipe 1, and the boiler, and a hot water pipe 5 isshown leading from a suitable source to the waste pipe .13, valves 5' ofany ordinary or approved type being arranged inisaid pipes to controlthe passage of the water through either pipe as desired.

' This cock comprises a two way casing 6,

thevertical bore 7 of which is of decreasingly-tapered form from itsouter end, the wall of said bore being slotted longitudinally atdiametrically opposite points, as at 8, to form openings for effectingcommunication between the tapered bore and the larstem 11, is formed ontheouter face of the casing in position to communicate with said inletport or opening 10, said stem being formed with an exterior thread 12,to adapt it for engagement with the waste pipe 13 which is connectedwith the hot water pipe 5. Y

It will-be obvious that any number of branch pipes may lead from themain hot water pipes as are desirable, this constituting a part of thewater-distributing system and not the invention, and therefore not beingshown in connected position. The wall'ot the tapered bore is also formedpreferably at a point in alinement with the port or opening 10, andinwardly of the same, with an outlet port or opening 1 1, for permittingthe drainage of the waste water from the cold and hot water pipes whenthe valve member or plug is in a closed position. A discharge pipe 15 isscrewed in the valve casing, and communicates with said lastmentio-nedport, the purpose of which will be apparen The numeral 16 indicates thebody of the valve member or plug 17, which is of tapered fOlllTtOclosely fit the tapered bore of the casing, and is formed with alongitudinal slot 18, adapted for registration with the openings of saidbore. An inlet port 19, leads fromone of the walls of said longitudinalslot 18, and is adapted for registration with one of the openings of thecasing when the valve member is turned to cut off the water supply.

A right-angularly disposed extension 20, is formed at the upper orenlarged end of the body 16, of the valve member, and is arranged tohave its outer portion extend inward, said portion constituting a finger21, adapted for engagement with either of two outwardly projecting lugsor stops 22, formed on the valve casing, said finger and stopsconstituting means for limiting the movement of the valve member, orplug, to permit of the latter being adjusted in either of its twopositions. The body of the valve member or plug is prolonged or extendedabove the finger 21, and a handle- 2st is removably fixed to the body bya fastening screw or other equivalent means, or the handleQ may beextended above the floor 23 as shown in Fig. 1.

In practice, the valve member being arranged in an open position, seeFig. 2, the water in the supply or service pipe 1, is permitted tocirculate to the boiler, and from there to any suitable connections,such as a sink, bath-tub or the like. hen it is desired to cut off thewater supply, the valve member or plug is turned in a positionright-angles to that shown in F 2, to bring the inlet port or opening19, thereof, in registration with one of the openings of the casing.this position the water supply is cut off, and the waste water in thehot water pipes passes through the inlet port 10 of the easing throughthe slot 18. and thence through the outlet port 14;, and is dischargedthrough the discharge pipe 15, the cold water passing through the inletport 19 of the valve member body and also out of the discharge pipe.

Although I have specifically described the combination, construction andarrangement of the several parts of my invention 1 do notconfine myselfpartlcularly to such specific.

When the valve member is incombination, construction and arrangement, asI claim the right to make such changes and modification therein as mayclearly tall Within the-scope of my invention, and which may be resortedto without departing from the spirit or sacrificing any of my patentablerights therein.

Having described my invention, what 1 claim as new and desire to secureby Letters Patent, is

A stop and waste cock of the class described, comprising a casingprovided in one side with a pair of vertically alined trans.- verseinlet and waste ports, and a revolubl'e plug having a longitudinalpassage and a waste port extending transversely through one wall of saidpassage, said plug adapted to permit the passage oi a fluid in eitherdirection when turned to bring its longitudinal passage intoregistration with the longitudinal bore of the casing, but adapted tocut off the passage of the fluid when turned to bring its longitudinalpassage across or at right angles to said bore of the casing and itswaste port in communication with said bore and to permit the waste fluidfrom one source to pass directly through the longitudinal passage of theplug to the waste port of the casing and the waste fluid from a secondsource to pass through the inlet port of the casing and the longitudinalpassage of the plug to the waste port of the casing.

In testimony whereof I aflix my signature, in presence of two witnesses.
